879141

The 879141 solenoid coil is produced by Vickers within the Vickers Hydraulic Accessories series and is intended to energize directional or pressure valve pilot stages in automated hydraulic circuits. It operates on AC and carries the B coil code assigned by the manufacturer. A DIN form factor is used for the winding assembly, and the design is rated for full power duty to maintain consistent magnetic force throughout extended cycles. Electrical connection is completed through an ISO 4400 (DIN 43650) rectangular plug that provides sealable contacts for fluid-zone mounting. The coil accommodates universal mains because it is compatible with 50 Hz and 60 Hz supplies; at 110 VAC and 50 Hz the steady-state current is 0.85 A, while at 120 VAC and 60 Hz the draw falls to 0.69 A. This broad electrical envelope allows a single catalog item to support machinery built for either North American or European power infrastructure.

Compact external dimensions simplify manifold layouts; the body length is 2.900 in, width is 2.700 in, and height is 1.800 in, so adjacent valves can be placed with minimal clearance. Total mass is held to 1.0 lb, permitting quick field replacement without lifting tools and keeping overall actuator inertial load low. The rectangular footprint matches the envelope of common Vickers wet-armature valve tops, enabling drop-in substitution during service activities. Because the coil generates its magnetic field at the designed ampere-turns, the housing is proportioned to dissipate heat through natural convection without external cooling hardware. The length dimension supports enough winding depth for the specified ampere-turns, while the narrow width allows side-by-side mounting on multi-position bar manifolds. The height measurement places the connector above most hose fittings, reducing the chance of oil splash reaching the ISO 4400 interface and maintaining reliable operation in production hydraulic automation systems.
